Application filed August 30, 1926. SeriaI No. 132,477.

This invention relates to weather strips for roofing.

In covering roofs with shingles of tile, slate, or other material, thepractice has been to render the roof water-tight by laying the shinglesin courses in such a manner that at all parts of the roof area therewere not less than two layers of shingles between the exposed uppersurface of the shingle asseml0 bly and the roof sheathing in order thatall exposed vertical joints could be underlaid with respect to the upper'or unexposed end of another course of shingles, for the purpose,mainly, of providing water conducting gutters at the interstices betweenthe adjacent shingles of each course.

The roofing system above outlined is suitable where relatively thintapering shingles are employed; but with thicker shingles having littleor no taperas flat tile, for example-such a method is objectionable onaccount of the quantity of material required to lay the roof by thismethod.

The object of my invention, generally stated, is to provide alight-weight, inexpensive, easily applied and efiicient device which maybe used in lieu of a large proportion of shingles which have hithertobeen requisite in the laying of a water-tight roof.

More specific objects and advantages of the invention will appear in thefollowing description.

The invention consists in the noval construction, arrangement andcombination of ."5 iarts hereinafter described and claimed.

In the accompanying drawing,-

Figure 1 is a top face view of a portion of a tile roof embodying thepresent invention; Fig. 2 is a longitudinal vertical sec 1 tion taken online 2-2 of Fig. 1; Fig. 3 is a detail sectional view on line 33 of Fig.2,. the upper course of tile being omitted from Fig. 3; and Fig. 4 is aperspective view of the weather strip which is utilized in the precedingviews.

Fig. 5 is a view similar to Fig. 2 illustrating a modified constructionof roof; and Fig. 6 is a perspective view of the weather strip used inthe roof construction illustrated in 'Fi 5.

eferring first to Figs. 1 to 4, inclusive, 10 represents roof boardswhich are secured in a well-known manner to the framework (not shown) ofa roof structure; and 11 represents roof paper, or an equivalent, whichis customarily employed u on the u er surface of a roof board ass mbly.PP

12, 12 and 12 represent shingles or tile, as they will hereinafter bedesignated, of three roofcourses. The tile shown in Figs. 1, 2 and 3,being of the type which is conventionally known as flat tile, each beingof a substantially rectangular shape and of substantially the samethickness throughout.

The tile of the respective courses are laid in side by side relationwith relatively narrow spaces 13 therebetween. The tile of eachsucceeding course, after the first course, are laid to slightly overlapthe tiles of the course next before laid. In accordance with the presentinvention such overlapping portions are insufficient to bridge thedistance between the lower edge, as 14, of a superposed course and theupper edge, as 15, of the next lower course; in other words, there isspace between the lower and upper edges 14 and 15, respectively, of thealternate courses of tile.

The tile in the successive courses, however, are laid in a manner tobreak joints with each other-that is to say, to have the interstices 13of each course outside of the planes of tile interstices of the coursesnext above and below the respective course.

'F or each of the interstices between adjacent tile of every coursethereof, I provide a weather strip (see Fig. 4) comprising a strip ofsheet metal, preferably copper, whichis pressed or otherwise formed witha cross section of substantially the shape of an inverted capital lettercentral ridge 17 with laterally protiuding flanges 16.

The flanges 16 are grooved or corrugated to provide in the upper surfaceof each flange one or more gutters, two being shown, which are indicatedby 18 and 19, respectively.

The ridge 17 and the gutters 18 and 19 extend longitudinally of aweather strip for the entire length thereof or nearly so.

For use with flat tile, as shown in Figs. 1 to 3, a weather strip isprovided at an end of each with upwardly directed lugs 20, constitutinghook elements to engage against the upper ends of the tile which areseated upon the respective flanges.

Thus arranged, the ridge 17 of a weather strip extends upwardly into theinterstice between the proximate side edges of the tile T to provide aand serves toprevent lateral displacement of the weather strip wi hrespectto the tile which are thereby supported.

In practice, the tile areulaid in approximately horizontal courses,beginning with the lower course of tile 12. The roofer disposes the tileand weather strips alternately, nailing each tile in place and hookingeach weather strip over the upper edge of the tile.

- The weather strips and tiles 12 of the next course are next placed inoverlapping relation with the tile of the first laid course and the tile12 secured by nails, the weather strips and tiles, 12 are then laid, andso on with each succeeding course until the weather strips and the tilefor the entire roof area are laid. The nails for securing the tile arerepresented by 21 in, Fig. 1.

. In Fig. 5 I show a modified form of tile, denoted by 120, 120 and 120for therespective courses of a roof. The individual tile beingcharacterized by each having along its upper edge a downwardly extendingflange 23 which is engageable with one of a series of cleat elements 22vprovided therefor on the roof structure.v

For the flange type of tile shown in Fig. 5, the weather strips aresimilar to those explained above for the flangeless type of tile exceptthat the lugs or flange extensions, denoted by 20 are turned downwardlyinto engageable relation with the root cleats 22, see Fig. 5, whichretain the tile in place.

It is to be noted that the tile are secured to a supporting roof framestructure; as, for example, by means of nails 21 (Fig. 1) or by means offlanges 23 (Fig. formed upon the tile, engaging roof cleats 22.

The weather strips, however, are connected either to the tile directlyor to the cleat to which a tile is coupled, the purpose being to" simplyretain the weather strips in Opera 'tive relations with the tilespertaining thereto. It is also to be noted that my improved tween spacedapart alternate courses of tile.

The grooved flange elements 16 of my improved weather strip ext-endbelow the associated tile of the respective courses to afford guttersfor conveying away any water enter ing the intersticesbetween the tile.The

ridge 170i a weather strip is of less height than the thickness of atile and by locating the flanges entirely below the tile of therespective courses, the weather strips are hidden from view and do notrender a tile roof unsightly.

The term tile as hereinbefore employed is not intended to limit myinvention for use with a clay product exclusively, as it may beadvantageously employed with slate and other kinds of shingles.

What I claim, is,

1. A weather strip for a shingle root comprising a metal stripconsisting of a transversely folded sheet of metal having alongitudinally extending laterally folded ridge and two laterallydisposed flanges longitudinally grooved, and having at one end, lugsprojecting at right angles to the planes of the flanges, adapted toengage the upper edges of the shingles.

2. A weather strip for a shingle roof embodying a struck up metal st "iphaving a longitudinally folded ridge, adapted to extend upwardly betweenthe adjacent edges of two shingles on tiles and havinglaterallyprojecting flanges, longitudinally corrugated to form gutters, andformed with end flanges bent perpendicularly to the plane of thecorrugated flanges and adapted to abut against the ends of the shinglesat the side of the central ridge of the strip.
